Hello and welcome to JustAnswer. I would like to try to help you. I am an expert from Germany and work with language translators. I hope that you will understand me. The telephone service is provided automatically by the system. Please ignore it. I CAN'T USE THE PHONE.
There can be several reasons why it does not work.
Explanation of the error code
Error code: F:21 (F21) or E:21 (E21)
Valid for: Washing machines from: Bosch / Siemens / Neff / Constructa (...) from year of construction 2009
Meaning of the error:
Drive failure: Motor does not rotate at all or starts up uncontrolled. A short circuit or interruption at the tachogenerator is also possible.
Motor and the control cable to the control electronics must be checked.
But you can try to delete the error once. Here is an instruction how to do it.
Switch off the machine
Close the door
Turn the program selector switch clockwise to position 6
Press and hold the speed selection key
Turn program selector switch one step further in direction 7 o'clock
Release speed selection button
The display (if present) now shows/flashes the last error
Now turn the program selector switch to 8 o'clock and wait a moment (8:88 in the display if available)
Switch off device
I'll be back online at 6:00. You can always send me a message then.
Do you have any further questions? Please write your message in the text field below. I AM WAITING FOR YOUR MESSAGE. Greeting Erdal Zal
